About These Birds
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
Magenta Petrel
38–42 cm. Large dark-rumped petrel; brown above with pale forehead and whitish underparts. Critically Endangered; rediscovered in 1978 on Chatham Islands. Fewer than 150 known pairs; threatened by introduced predators and road lighting. Feeds on squid and fish at sea.
